NOVA is a 3d voxel display. It was developed by ETH Zurich together with private companies. NOVA at Mainstation Zurich is made of 25'000 voxels (each containing 12 LEDs). It has a refresh rate of 25Hz and a color resolution of 24Bit (16,777,216 colors), which makes it pretty amazing :-).

horao gmbh, an ETH spin-off company, is further developing and marketing NOVA.

Realtime visuals on the NOVA (2012, Mainstation Zurich) for Steve Reich's „Different Trains” performed with the Collegium Novum Zürich. Form, colors and transformation of the visuals are being controlled based on the fast fourrier transform algorithm.
